functions for fault conditions. When a fault condition occurs, the engine
will shut down and the LCD panel will display the fault causing the
shutdown. To reset the Engine Control Module and resume operation,
return the Engine Start Switch manually to off “O”. Also refer to Section
Warning Light.

Indicates that the engine speed exceeded
approximately 2000 rpm (110% of its rated
speed of 1800 rpm) and the ECM has auto-
matically shut the engine down.
An overcrank fault is displayed when the
engine fails to start during the normal cranking
cycle, and the Engine Control Module has
automatically shut down the generator due to
an overcrank condition.
A low fuel fault condition will be displayed
when the fuel tank drops to 5% and the Engine
Control Module has shut the engine down.
This fault condition prevents the fuel lines from
running completely dry and avoids the need to
bleed the lines when the tank is refilled.
Indicates that the engine speed dropped below
55 Hz for more than 15 seconds and the ECM
has automatically shut the engine down.
